Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18192, here are decompositions:
- 11 + 18181 = 18192
- 23 + 18169 = 18192
- 43 + 18149 = 18192
- 59 + 18133 = 18192
- 61 + 18131 = 18192
- 71 + 18121 = 18192
- 73 + 18119 = 18192
- 103 + 18089 = 18192
Showing the first eight; more decompositions exist.
